The invention discloses a large prefabricated structure undocking method based on an own traction system. The traction system comprises a winch and a steering saddle on the top of the prefabricated structure, a cable tying column on the top of the dock wall and a cable. At least four traction systems are arranged. The method comprises the following steps: step 1, for a traction system at the front part of a prefabricated structure, connecting a cable with cable tying columns on two sides closest to a dock entrance; for the traction system at the rear part, a cable is connected with the cable tying columns at the two sides at the rear part; 2, injecting water into the dock; during water injection, according to the height difference between the prefabricated structure and the top of the dock wall, all the sets of winches are started to take up and pay off the cable; 3, a winch is started to synchronously tighten the front mooring rope and synchronously release the rear mooring rope so as to pull the prefabricated structure to move to the dock entrance; 4, the left rear portion and the right rear portion of the prefabricated structure are connected with the adjacent cable tying columns through auxiliary ropes; connecting the rear cable to a cable tying column closer to the prefabricated structure; and then the auxiliary rope is removed.

    本发明公开了一种基于自有牵引系统的大型预制结构物出坞方法。所述牵引系统包括预制结构物顶部的卷扬机和转向鞍、坞壁顶部的系缆柱,以及缆绳。牵引系统至少有四组。所述方法包括:步骤1:对预制结构物前部的牵引系统,将缆绳与最靠近坞口的两侧系缆柱连接;对后部的牵引系统,将缆绳与后方的两侧系缆柱连接;步骤2:往船坞内注水;在注水时,根据预制结构物与坞壁的顶部高差,启动各组卷扬机对缆绳进行收放;步骤3:开启卷扬机以同步收紧前方的缆绳,并同步释放后方的缆绳,以牵引预制结构物移动至坞口处;步骤4:借助辅助绳将预制结构物的左后部、右后部与邻近的系缆柱连接;将后方缆绳换连至更靠近预制结构物的系缆柱上;随后解除辅助绳。
